Hard oil line advice
 

If you remember me at all, you'll recall that I don't know much about my 911 SC, but I want to learn and I've been working on projects as they come up. Here's the latest. I've had an oil problem for a bit and discovered the culprit was a hard oil line. Not knowing which is the supply line and return line, I called Pelican and said it was the line that was visible below the rocker panel.

They said it was the supply line and I ordered the part.

Fast forward. After a little struggle, I removed the line with the leak. When I tried installing the new one, I discovered the new Porsche part and the old one were different (in the pic below, you can see the new part is a right angle and old one is curved upward). At first I thought it was the wrong line, but John Walker helped determine (in his post below) that it's the right line. How am I supposed to install when the part doesn't reach the thermostat? Am I supposed to reshape the pipe?

Thanks for your wisdom.

OK, here's the pic
 

Thank you!

One has a bump to clear the jack point and one doesn't.

Thanks for pointing that out. The one with the bump is not the one I am replacing. So it seems I have the right part. Manufactured by Porsche for my car. But it won't fit. The end that attaches to the thermostat should curve upward (as the original one did, as you can see in the picture). Or maybe this part is fine and it's user error? Any suggestions?

Here is the other option Pelican offers. The one made by Porsche is a right angle on one end and the OEM part is curved. This strikes me as a mistake on Porsche's part.

No other lines, they're all the same. The old 911 prefix superceeds to 930 is all.

I'm a little confused. Do you not agree that in the picture I shared the two lines are shaped differently on the thermostat end? The new one is a right angle (and about three inches shy of reaching the thermostat) and the old one is curved (and reaches the thermostat).

The two new supply lines share the same differences: the Porsche line is squared at one end and the OEM part is curved.

If I'm am correct the Porsche part is too short to reach the thermostat because of the right angle, how would you go about attaching it to the thermostat?

I thought 73 and earlier lines had some differences?

I found these listed for a 74-77?.?????http://forums.pelicanparts.com/uploa...1654525987.jpg

74-77 has no external cooler so that is odd.

why dont you tell us what part number you actually ordered ? i think that would be the first thing you posted.

also a pic of the whole line would be good.
Also lets open the discussion to other possibilities.
On an sc are the flexible connections differing lengths or the same ? I dont know but perhaps someone could answer that , Also are yours the same or different ? perhaps someone rebent it to fit previously ? ( as it is VERY rare for these guys to leak so you have to wonder about the initial leak anyway. ) .

Sounds like you need a longer flexible connection line than what you currently have on the car if the line is in fact correct , has it been upgraded from the original trombone by chance ?

Didn’t say it was correct. Oil hose return pipe Porsche 911 74-77 material: brass reference: 911.207.046.00 91120704600.

Not Compatible.........
 

The 90° bend oil line is not compatible with old OEM brass oil line. The location of the nut would be the problem. As you have shown them side by side, it won’t fit with the other OEM oil line installed. Unless you use a set of the 90° bend oil lines. This is like buying a pair of sneakers made by different manufacturers and different configuration/model.

You could see the discrepancy by comparing them side by side and the problem is very obvious. The configuration of the oil lines are completely not compatible to each other.

On the guidance of Pelican, I ordered Porsche part # 930-207-045-03 for an 81 911 SC.

I removed the old line and waited to receive the shipment from Pelican.

When I got the part, I tried installing it but the line wouldn't reach the thermostat. I then laid the old pipe (which had a leak) next to the new one and discovered that they are not the same design.

Apparently I need part # 930-207-045-03-M260.

The cooler is no longer a trombone--it's been upgraded.

The thermostat is not after-market.

This is all I know. I just don't understand why there are two differently designed parts that are supposed to fit an 81 SC.

ok now we have the rest of the story ......
the trombone cooler has unequal lengths and im sure the oil lines would have fit that , you have a different type of cooler now and i bet the original oil line was bent to match or is a different line . i think if you got different oil hoses that connect the two it would work. All bets are off once you tell us the oil cooler has been upgraded, you are no longer discussing an SC config with SC parts.

The way i understand the OP it is too short vertically, not horizontally. Or?

Exactly........
 

The replacement oil lines (90° bend) is not compatible with the old OEM hard oil lines. Either buy a set of the new oil lines or get one that is exactly the same as the old one.
